The PA22 is a contactless palm recognition terminal powered by Computer Vision Technology and ARMATURA, featuring 3-in-1 biometric authentication. It simultaneously verifies the palm vein, palm print, and palm shape once a hand is detected. Equipped with a 2.4-inch high-resolution screen, a touch keypad, and an intuitive interface, the PA22 delivers fast and reliable recognition. Its angle tolerance reaches ±60° on the roll axis, and it supports a maximum recognition distance of 0.35 meters, depending on the palm size. The terminal can identify a palm in as fast as 0.4 seconds, ensuring smooth and efficient operation. For enhanced security, the PA22 adopts the AES-128 encryption standard, safeguarding all biometric data.
